Application led May 3, 1916. Serial No. 95,186.

ince of Manitoba, in the Dominion of Can-y ada, have invented certain new and useful Improvements in Convertible Tables, of which the following is a speciiication.

My invention relates to tables more particularly useful in apartment blocks, hotels and vessels, where such are required only'at certain hours of the day, while a large seat-4 ing capacity is in demand at all times, and the object of the invention is to provide a device which may be used as a table at meal hours and thereafter be readily converted into a plurality of chairs. The means by which this change is accomplished will be foundl fully described in the following speciication and then more particularly pointed out in the appended claims, reference being also had to the accompanying drawings which form a part hereof and in which similar characters vof reference refer to similar parts throughout the different views.

In these-.Figure 1 is a plan view of the device with the parts thereof positioned to form a table. Fig. 2 is a section taken substantially on the line 2-2 in Fig. l. Fig. 3 is a side elevation of the device with the parts positioned to form chairs. Fig. 4 is a sectionall side elevation of one of the chairs.

Fig. 5 is a front elevation of the same. Fig.

6 is a view of one of the corner pieces that occupylthe spaces between the chairs and complete the. contour of the table top. Fig. 7 is a plan view of the rotatable casting to which the chairs are hinged. Fig. 8 is a plan view of the lower casting by which the radial chair supports are carried. Fig. 9 is a view of the under side of the central portion of the table top and its maintaining member. Fig. 10 is the lever by means of which the central portion of the table top is raised to allow of the rotation of the chairs to lower the same.

In the drawings 3 indicates the base of the structure, preferably a casting having openings therearound at spaced distances for the reception of the ends of the legs 4, the latter being provided with caster wheels 5 of any preferred type. The base 3 may also be pro vided with a caster wheel support if such be in normal position.

considered necessary, but the application is self evident and does not require illustration.

The basev3 is bored in two dimensions, the smaller to provide a socket for the reception of the lower end 6 ofthe table leg 7 and the larger to provide a space Sgaround the said leg 7 to receive a ring 9v rotatably therein,

balls k1Obeing preferably disposed in the space 8 below the ring to avoid friction.

The leg 7 is provided at the top with a cap 11 forming a support for the central portion 12 of the table top, the said portion having secured thereto a rectangular member 13 which passes slidably down through an opening of similar shape formed through the leg 7 and projects slightly below the same. The shape of the member 13 and of the opening through which it passes prevents any rotary movement of the portion 12 of the table top.

A lever 14 having a toe 15 engaged ina depression 16 countersunk in the lower end of the member 13 provides a Vsuitable means for raising and loweringV the member 13 and with it the portion 12 of the table top when occasion demands it, the lever 14 being fulcrumed at the point 17 and having a vertical member 18 connectedl thereto and passing up through one of the legs 4 upon which foot pressure may be exerted to operate the lever. A coiled spring 19 is positioned around the member 18 to maintain the lever The leg 7 isl eXterorly screw-threaded as shown and a casting 2O having'a bore 21 to it the leg 7 is interiorly screw-threaded to engage the threads on the leg and is mounted thereon, the cap 11 limiting the upward movement of the casting 20 on the leg 7.

The casting 20 is provided with wings 22 extending out to meet the chairs 23 a pluis elevated into contact with the cap 11v 20 von the leg 7 of the table, the'backs21vof the reception of the ends of the radius rods and31 pertaining to each seat, the rods being pivoted thereto and to the clips on the seats to connect the same.

It will be observed that the radius rods 30 and 31 diverge as they leave the ring 9, sodthat the chair seats are supported at each s1 e.

The central portion 12 of the table top the chairs are in horizontal position and form part of the table top, triangular pieces being-positioned to fill the angles between the same and complete the contour of the table top.

As it is necessary that the pieces 35 be removable the edges ofthe chair backs 24 l are provided with grooves36 to receive the tongues 37 formed on the edges ofthe said triangular pieces 35. When in theposition described the device provides a table having a top formed from the central portion-12, the backs 24 of the chairs and the triangular pieces 35, the said top being of any pre-g arranged size and shape.`

When it is desired to convert the table into chairs the corner pieces 35 are removed and pressure applied upon the pedal member 1S to elevate the portion 12 of the table top,r thus unlocking the Achairs 23 and allow-V ing them to be rotated around the leg 7, the rotative movement being participated in by the casting 20, 'the ring 9 and the radius rods 30 and 31. As the movement continues the casting 20 descends upon the leg 7 carrying with it the chairs 23 the seats 28 of the latter being gradually forced into horizontal position by the changing position of the radius rods 30 and 3l. Uien the casting 20 reaches the portion of the leg 7 where the screw-thread ends, the movement is complete and the table has become a plurality of chairs, as shown in Fig. 3 Y

A ln Figs. 3 and 5 it will be noticed that the edges of the chair bottoms 2S are provided with longitudinal grooves 39 and the cornerV pieces 35 are` now positioned with their tongues 37' engaged Vin the said grooves 39, thus'forming shelves between the chairs for thereception of books or other articles. rThe positioning ofthe corner pieces 35 between the chairs also serves to lock the Y same in their new position which cannot be changed without the removal of the said corner pieces.

that the number of chairs which it may be made to provide is not limited tothenumber shown in the'd-rawings but may be increased to any'reasonable number by in creasing the sizeof the article;

' It will be` further understood that this f specification is intended to ben'descriptive ratherpthan exhaustive and that l! claim as mine any variation of the means shown as can be properly construed as 'coming within the lspirit of the Vinvention or within-:the

scope of the appended claims.

VVhatl claim is f" 1. A table having a leg, a plurality lof chairs radially ldisposed around fthe leg,

means connecting *the lchairs and leg, andY operative to position top of the table.

2. A tablehav'ing a leg,

the chairsto form the Y legfmeans connecting the chairs an'd leg, and operative to elevate the chairs and position them to form the top Aof the table.

3. A table having a leg, a plurality. of

y a plurality of, outwardly' facing chairsy disposed about the Y around the leg, and' means operative to elevate and simultaneously rotate the chairs to position the backs thereofto form' the tabletop. v Y f f1. A table having a leg, a'plurality of outwardly facing chairs radiallydisposed around Vtheleg, means movably mounted on the leg and pivotally connected to Vthe chairs to elevate the-same, and means to simul- 1110 'taneously rotate the chairs to cause the backs thereof to assume a position constituting them a part of the table top. Y

5. A table having an exteriorly screwthreaded leg, a member mountedon theV leg and interiorly screw-threaded for engagement with the threads thereon and having wings, ay plurality -ofl outwardly facing radially disposed chairs pivotally connected to the said wings, a member rotatively mounted on the leg adjacent the bottom thereof, and radius rods pivotally connect` liong the cha-irs and rotatively mounted mem- G.' 'A table provided with a Vcomparatively n small vertically movable top having a plurality of sides and a leg by which it is sup'- ported, chairs equal in number to thefsides of the top radially arranged around theleg, means operatively connecting the chairs vand 100 outwardly facing chairs radially disposed leg and movable thereon to elevate and rotate the chairs simultaneously whereby the backs thereof are brought into coincidence with the plane of the table top and the lower edges of the backs into contact with the sides of the said top, and members shaped to fill the spaces between the backs of the chairs to complete the contour of the enlarged table top.

7. A table having a vertically movable top and a leg upon which it is normally supported, a plurality of chairs normally faced out radially around the leg, means to elevate and simultaneously rotate the chairs to cause the backs thereof to assume positions as part of the table top, lever means to release or lock the chairs in their last named position through movement of the vertically movable portion of the table top, and members shaped to fill the spaces between the chairs and provided on their edges with means adapted to interengage with means on the edges of the chairs whereby they may be positioned to complete the contour of the table top when the chairs are in elevated position or to form shelves between the chairs when the latter are in normal position.

In testimony whereof, I affix my signature in the presence of a witness.
